Re: Measuring the output power

This looks like a nice product! I may just buy one.
The SWR bridge is a circuit I am familiar with. I built an SWR bridge using this circuit for the 2200 and 630 meter bands (136 and 475 kHz). I used two separate toroids made with number 77 material.

I had forgotten that QRPGuys makes a nice little power meter accessory. ? for $40.? It was very easy to put together and includes a QRP dummy load on the board.? I think I built it in one night.? I have it sitting on a shelf under my station monitor.? It is battery operated so I only connect it when I need to verify power and my other meters.? It is a very handy device.? You need to wind the transformer but that is the hardest part of the kit.? It is very small and there is a 3D printed box that you can make too.? They use PayPal as an interface for payment and shipping.? Please see their for details.
